System Clock Loses Time

The clock on the Windows 98 taskbar can lose time, and it may get worse the longer you use the computer. Here are some tips and fixes.

What Happens and Why

There is a "CMOS clock" in your computer which is powered by a tiny battery. As long as the battery is good, this clock keeps the correct time, and each time your computer is restarted, Windows98 reads its initial time from the CMOS clock. However, while Windows98 is running, it keeps track of the time on its own without continuing to check the CMOS clock, and keeping track of the time is not the only thing Windows has to do. The busier your system gets, the more likely it is to lose time. Generally, the longer you use your computer, the further behind it gets. When you leave your computer on for an extended amount of time, the Windows clock (displayed on the taskbar) may lose from two minutes to an hour per day.

Likely culprits

Anything that makes your computer especially "busy" can take Windows' attention away from its time-keeping function and lead to this "losing time" symptom. If you're running lots of programs, or even just one or two very demanding programs, you may see the computer clock losing time. Furthermore, anything you are running which causes the computer to have to spend time "watching" for something to happen can also lead to a slow clock. Here are the most common culprits:

What you can do

 

Setting the CMOS clock

If Windows displays the wrong time when it first starts, your CMOS clock may need to be set. If you have to do this repeatedly, your CMOS battery may need to be replaced (call the ITC help desk at 924-3731 for assistance). Here's how to set the CMOS clock:
